Description
Technical field
The present invention relates to medical products field, a kind of specifically elbow cane.
Background technology
Crutch is a kind of important medical rehabilitation appurtenance, and usual crutch is divided into walking stick, elbow cane and crutch, wherein walking stick
It is mainly used in slightly needing, such as the elderly or climber, elbow cane belong to moderate lower limb disability people's articles for use,.Crutch is lower limb weight
Spend handicapped person's (invalid disability etc.）Necessity.
Among the use process of elbow cane, because most of pressure of human body will be concentrated in hand handle, usage time is long
, palm and arm are especially ached, or even arm can be caused to damage under some feelings.
Application No. 201610665395.6, a kind of entitled elastic crutch disclose a kind of crutch, including lower bracket,
The top of lower bracket is connected with middle bracket bar, and the top of middle bracket bar is provided with crutch handgrip, crutch handgrip and middle part
Bar cradling piece is threadedly coupled；The lower bracket includes lower bracket bar, and the top of lower bracket bar is socketed on middle bracket bar
Outside, the lower end of lower bracket bar is fixedly connected with some support bars；The middle bracket bar is hollow tube, middle bracket bar it is interior
A upper support chip is fixedly installed in portion's cavity, lower bracket bar is hollow tube, is fixed in the internal cavities of lower bracket bar
It is provided with one and props up
Blade.
The shortcomings that above-mentioned crutch, is：First, when not clamp less power, crutch will be deformed, so
On the one hand crutch can be caused especially unstable, had using hidden danger；Second, when clamp larger power, deformation ratio is larger.
The content of the invention
In order to solve the above problems, the invention discloses a kind of medical elastic elbow cane, including：
The contact surface of first stick stem and the outer tube being connected with the first stick stem, the first described stick stem and outer tube is recessed provided with one
Portion；
Interior bar, described interior bar are located at outer tube, and one end of interior bar is protruded into the recess of the first stick stem, and the other end is connected with
One hand handle, outer tube are provided with the active tunnel that hand handle passes through so that hand handle can move along the axial direction of outer tube, interior bar
A retainer ring is provided with, spring is provided between retainer ring and the first stick stem；
Elbow frame, elbow frame include a gland that can be fixed on outer tube, and the axial portions of gland are provided with a through hole,
Knob is connected with through hole whorl, interior bar is withstood in one end of knob, and the other end is provided with rotary torsion portion.
In the present invention, the first stick stem can be integrated molding with outer tube or be fixedly connected, use when
Wait, interior bar is put into outer tube, outer tube and the first stick stem are connected（When needs）, hand handle exposes from active tunnel,
Elbow frame is fixed on outer tube by gland, knob is arranged in gland.When in use, turn knob, interior bar
Pushed up toward bottom so that spring-compressed, the compression stress certain to spring, in the case of not considering elbow cane gravity, the compression stress of spring
For F, knob is also F to the pressure of interior bar.When people uses, when the pressure to hand handle is less（Less than F）, this
When spring will not deform, interior bar and the first stick stem will not move axially, and whole elbow cane is in a kind of rigid state, when
Human body is larger to the pressure of hand handle（More than F）When, this when, knob and interior bar will separate, and compression will continue to press
The state of elasticity will be presented in contracting, interior bar and the first stick stem, will buffer the instantaneous pressure of hand handle meeting human hand significantly, reduce opponent
Damage.
In some preferred embodiments, described interior bar is provided with and the circular groove of knobs fit, knob are deep into circular groove
It is interior, any device can not be set in circular groove, bearing etc. can also be provided with, when its object is to reduce knob and interior bar
Radial frictional force, but it is also possible that knob can be free to exit interior bar in the axial direction.
As a further improvement, hand handle and interior bar can be connected firmly in interior bar with integrated molding or removably, such as
If fruit integrated molding, active tunnel is relatively the structure of an opening, can so cause hand handle to enter active tunnel, such as
Fruit is when removably connection, and active tunnel can be the structure of closing.
As a further improvement, so hand handle can be prevented to be moved through the axial direction command range of active tunnel
Greatly, cause unstable, but only active tunnel has less distance, such as 1 centimetre to several centimetres, it is possible to larger to hand handle
It is living spring, buffering effect can be played.Knob control F can be adjusted according to factors such as the body weight of user in the present invention
（Threshold value）Size, body weight is relatively low can to control that F is a little bit smaller, and body weight is big, and F is a little bigger, and so this elbow cane can meets different
Age different weight Man's Demands.Existing conventional retractor device can be provided with certainly for the first stick stem, meets different bodies
High Man's Demands, the first stick stem are usually solid, but can also be provided with hollow device.
The material of each part can use conventional material in the present invention, but in order to do not lower intensity and
So that in the case that product is more light, present invention uses a kind of special foam metal material to prepare the first stick stem, outer tube.
In the present invention, described foam metal is prepared by powder metallurgy method, and wherein raw material includes according to parts by weight：
Aluminium：100 parts, the zinc of 2-5 parts, the rare and scatter element composition of the copper of 2-5 parts and 0.2-2 parts.Wherein also include rational impurity member
The element that plain carbon etc. can not remove completely, the weight ratio of carbon impurity element are closed typically under 0.1% by adding
The zinc and copper and rare and scatter element of reason ratio, the crystal compactness of aluminium base can be significantly improved, improve the mechanics in smaller area
Performance, the intensity needed is kept when its porosity is larger, is compared with existing aluminum-base composite foam metal material, the present invention
The rare and scatter element of specified quantitative and zinc and copper are used cooperatively, in the case where the porosity is big, significantly improve its intensity.At this
In invention, gallium, selenium, indium, cadmium have preferable effect, particularly gallium element relative to other materials.
Its preparation method is as follows：
Step 1：Dispensing is carried out according to element ratio；
Step 2：The ball milling 24-48 hours in high energy ball mill, it is 2-5 μm to control particle diameter；
Step 3：Sintered under vacuum or inert gas conditions, it is 1-5mm, porosity 95%-97% to control aperture diameter.
It in step 3 kind, can start to sinter 0.5-1 hours under vacuo, secondly add the inert gases such as nitrogen, argon gas,
So when vacuum-sintering, a certain amount of impurity elements such as oxygen in metal can be removed, naturally it is also possible to from purity
It is prepared by higher metal.Foam metal prepared by the present invention has light microcosmic good compactness, amount, shock resistance, rigidity property good
The advantages that, it is adapted to use in wheelchair, crutch.
